I hope we watched tape of Atlanta's defensive coverage against them.
Everyone says this, but everyone forgets that Peyton shredded their defense after getting pictures in the 2nd Q. He figured that style of D out quickly. When the Raiders and Chargers tried to mimic it, he dropped 3 TDs on them.
In order to beat Peyton you must confuse him, which means throw him a defense he hasn't seen. He has already seen what ATL did, and it will not negatively affect him again.
